CLAY-SCREENING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 663,800, dated December11, 1900.

Application filed August 30, 1900. Serial No. 28,589- (No model.)

To a ZUhOWb it may concern.-

Be it known that I, HORACE G. VIRGIN, a citizen of the United States,and a resident of Penrith, in the county of Hancock and State of WestVirginia, have invented a new and Improved Clay-Screening Apparatus,ofwhich the following is a full, clear, and exact description.

The purpose of this invention is to provide means for screening clayused in brick-making; and to this end the invention comprises aninclined screen with a brush or a gang of brushes arranged therein andconnected with means for reciprocating them on the screen, so that thefine clay is sieved therethrough and the lumps of coarse clay are causedto gravitate down the screen into a suitable receptacle at the lower endthereof.

This specification is the disclosure of one form of the invention, whilethe claim defines the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan View of the invention. Fig. 2 is a vertical sectionon the line 2 2 of Fig. 1, and Fig. 3 is a detail section showing themeans for mounting the brushes.

The machine is provided with a suitable framing a and has an inclinedscreen I) sustained thereon, the screen being provided link 9 pivotallyattached thereto. This link has its opposite end connected with acrankshaft h, mounted in the framing a, and the crank-shaft is adaptedto have a rotary move ment imparted thereto. The longitudinal side railsof the frame f are supported to reciprocate on rollers f, adjustablyheld on the side walls 0 by brackets f By these means the pressure ofthe brushes on the screen may be regulated. If desired, the shaft h maybe connected with the conveyer by means of a belt 2', passing overpulleys it and Z, respectively connected with the conveyer andcrankshafts.

The clay being delivered to the upper end of the screen and the brushesbeing driven reciprocally on the screen, the fine particles of clay willbe forced through and the screen kept clean and free from clogging. Thecoarse particles of the clay will be precipitated down to and from thelower end of the screen.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A clay-screening apparatus, having an inclined sieve,a gang of brushes mounted on the sieve, a framing connecting the brushestogether, a link pivotally connected to the framing, and arevolubly-driven crank-shaft to which the link is also pivotallyconnected, for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HORACE G. VIRGIN.
